Papercup (RWS AI Dubbing)

Papercup, now part of RWS, combines patented AI voice technology with human linguistic expertise to create natural-sounding dubbed audio that resonates across cultural boundaries. The platform handles the entire localization workflow—from transcription and translation through voice generation and synchronization—eliminating the need to coordinate multiple vendors. This integrated approach reduces complexity and accelerates time-to-market for globally distributed content. The core strength lies in emotional authenticity. Papercup's AI voice models are trained on thousands of hours of licensed voice data and refined by a global network of over 1,800 in-house linguists and 40,000+ experts. This ensures dubbed content captures nuance, tone, and cultural context—critical for corporate communications, drama, news, and branded video. The three-tier human review process validates scripts, checks cultural sensitivity, and quality-assures pronunciation and pacing at scale. Measurable results demonstrate real business impact. Clients report 28x higher viewership for Spanish-dubbed tracks and 5x growth on German content, with dubbed videos consistently exceeding 1 million views. The platform supports diverse use cases: product explainers, training materials, social media, broadcast content, and internal communications. Enterprise workflows are fully customizable, secure, and scalable—with options to blend AI voices alongside professional human voice-overs when needed.
